MarmotHelium - Sleeping bag

The Helium is a remarkably lightweight and compact sleeping bag from the brand Marmot, offering optimal insulation for three-season hiking or trekking. Featuring a Pertex® outer shell, 800 fill-power goose down insulation, and a Down Defender waterproof treatment, the Helium keeps you warm and dry throughout your night in the wilderness. After a long day of mountain hiking, you can rest your feet in the spacious and enveloping footbox of the Helium. The smooth, curved baffles keep the filling in place, while the multi-baffle Nautilus hood with drawcord, snag-free insulated draft tube, and two-way zipper with anti-snag slider minimize heat loss. If you wish to cool down slightly, the secondary fold-down zipper allows for ventilation. Additionally, the Helium is equipped with an internal stash pocket for safely storing your small valuables.
